buying 07 H2, please help

[drmotorhead]

The salesman is telling me that they really dont negotiate very much on price. He is quoting a whopping $1500 off sticker on remaining 2007 inventory. I have never purchased a hummer before, but have bought other new GM vehicles, and there has always been lots of room for negotiation at the end of the model year. I am really looking for more like $7,000 off sticker, plus the 0% financing It sounds like a reasonable offer considering that the 08's are getting a little restyle and an upgraded engine.

Is the salesman working me over?
